Could've sworn I've seen Arcane being talked about around here somewhere. Guess my mind is going loopy lately :V
Anyways, Arcane, the League of Legends based animated series on Netflix. First off, no need to be familiar with LoL in any way, shape or form. The story is fairly self contained and can easily be an introduction to the lore of the games. You'll get a kick out of recognizing some things when they're introduced but it's in no way mandatory (also fuck the fact that english subs only offer closed captions which will spoil certain introductions a bit)
What the show is essentially is an origin story of multiple champions from the game, shows who they are, where they come from and how they relate to other champions. All of that is packed in a rather compelling story of multiple characters and factions, all with their own motivations and goals even if they aren't terribly new or complex, they mesh together very well to create an interesting story that moves along at a nice pace.
Now, the biggest thing, for me at least, is the visuals, I'm not sure what their exact approach is, but I'm suspecting a mash up of 2d and 3d, but it's done so seamlessly that it's hard to tell most of the time that it isn't hand painted. The style they've went for as well is brilliant, just the right amount of stylized and realistic proportions. Seriously, if for no other reason than to enjoy well made animation, it's well worth a watch.
